In projects such as municipal drainage and sewage treatment that need to be buried deep underground, the "pressure resistance" of the pipeline has always been the core test - the thick fill above and the load of passing vehicles are like a "heavy burden" on the pipeline. Traditional pipelines are often "hard to carry" by their own wall thickness, and they are prone to deformation or even rupture over time. The HDPE carat pipe of AD Pipeline can "become a partner" with the surrounding fill and bear this pressure together. This is its unique "common bearing capacity with fill" design logic, which also makes it show different advantages in engineering applications.

Let's talk about the principle of this "common bearing" first: The HDPE carat pipe adopts a ring-shaped corrugated structure, and the corrugations on the outer wall of the pipe can be closely integrated with the surrounding fill like a "breakthrough point". When the pressure from above comes, the pipe is not stressed alone, but transmits the pressure to the surrounding soil through the corrugated structure, making the soil a "force community". This design directly rewrites the force mode of the pipeline "alone", turning "individual pressure" into "teamwork". The first obvious advantage of

is to greatly increase the overall bearing capacity. For example, in a rainwater pipe network project with a fill height of 3 meters, the traditional HDPE pipe may need a wall thickness of 12mm to withstand the pressure, while the AD HDPE carat pipe can achieve the same load-bearing standard with a wall thickness of only 8mm because of the "help" of the fill. This is not "cutting corners", but allows the soil to play its due role - the corrugated structure allows the pressure to be evenly distributed to a larger soil area, which is equivalent to adding a layer of "soil shield" to the pipeline, which can be easily dealt with even if it encounters heavy-duty vehicle rolling. The second advantage of

is to reduce the material consumption of the pipeline itself. Because there is no need to rely on the wall thickness "hard support", the wall thickness of the AD HDPE carat pipe can be thinner, which not only saves HDPE raw materials, but also reduces the weight of the pipe. For example, a carat pipe with a diameter of 1 meter is about 30% lighter than a traditional pipe of the same size, which saves effort during handling and installation. This lightweight advantage is particularly obvious, especially in narrow construction sites. The third advantage of

is to enhance system stability. The underground soil is not "static" and will move slightly due to factors such as precipitation and settlement. If a traditional pipe is unilaterally stressed, it is prone to dislocation or fracture due to soil displacement; while the AD HDPE carat pipe can be "fine-tuned" with the soil through its close combination with the filling - when the soil settles, the pipeline and the surrounding filling deform synchronously, dispersing the stress and greatly reducing the risk of leakage. In a sewage treatment plant pipe network project in a northern city, after the use of AD carat pipes, the deformation rate of pipelines was reduced from 5% of traditional pipes to 1.2%, and the frequency of later maintenance was greatly reduced. The fourth advantage of

is to extend the service life. Traditional pipelines are prone to wear or cracks on the inner wall due to long-term concentrated stress; while the common bearing design of AD HDPE carat pipes allows the stress to be evenly distributed between the pipeline and the soil, reducing the fatigue damage of the pipeline. Coupled with the corrosion resistance of HDPE materials themselves, the service life of this pipe can reach more than 50 years, which is 10-15 years longer than traditional pipes.

Finally, there is the convenience of construction. AD HDPE carat pipes are lightweight, simple to connect (using hot melt or electrofusion connections), and have lower requirements for foundation cushions because they can bear the same load as fill - traditional pipes may require a thick concrete foundation, while carat pipes only need a flat crushed stone cushion to meet the requirements. For example, in a farmland water conservancy project, the use of AD carat pipes shortened the construction period by 20% than expected, and reduced labor costs by 15%.

From municipal drainage to sewage treatment, from farmland water conservancy to industrial pipe networks, AD Pipe's HDPE carat pipes have turned "pipes + soil" into a more efficient and stable system with the design of "common bearing capacity with fill". This design is not "unconventional", but based on the actual needs of the project - so that the pipeline is no longer an "isolated individual", but together with the surrounding environment, it becomes a "strong defense line" of the underground pipe network. For underground projects that need long-term stable operation, such pipes are undoubtedly a smarter choice.
